How to change velocity on different screens

hi all! My game use matter physics. The size 100% x 100%. But velocity in game is always different and it seems like depends on the size of the screen. But i cant figure out how exactly velocity relate to the screen size. Is there any particular dependance? Anyone bumped into such a problem? thnx!

Iv got the same problem! The screen definitely affects the physic speed and iv tried lots of things but nothing helps. The velocity is always different and I dunno if it"s even possible with MatterJS. Iv done some reading and the only suggestion i found is to use another physics engine like PlanckJS. Let me know if youll find any solution. Cheers! Good luck.
